Poor WAAS Performance with Veeam Backup and Replication

[ethernuts]

I have two wae-574's doing inline interception on a T1 line.  I'm doing Veeam replication across that T1 Line (or attempting to).  It appears that I'm getting roughly zero acceleration during the veeam jobs and it doesn't make much sense why.  Other applications are being accelerated.  The WAN to LAN statistics never jump over 1.5 megabit when running the job.  I'm not sure what to do at this point.

10.30.1.44 is my Veeam Box.  It's a Virtual Machine on the source side.  I've run the show stat command on the remote waas unit.

Veeam is setup to use appliance mode, with no compression (thinking the WAAS would do the magic).

RemoteCiscoWaas#show stat con | include 30.1.44
248287      10.30.1.44:54964        10.30.2.62:902 1c:c1:de:7f:de:cc T     00.0%
248345      10.30.1.44:54975        10.30.2.62:902 1c:c1:de:7f:de:cc T     00.0%
248386      10.30.1.44:55029        10.30.2.62:902 1c:c1:de:7f:de:cc T     00.0%

Any Ideas?

Thanks..

Bryan,

As it is right now only TFO has been enabled, thus you might see ANY gain only if a packet is lost.

I would first check if the application is setup for only TFO or is there a fallback to TFO only.

A good way to start would be to create a new classfier with high (order) number to perform TDL optimization for this particular TCP flow.

It works now! I had to set the VMware-VMconsole policy to full acceleration on each WAAS device involved in the Veeam traffic (thanks for the help on the veeam forum).  Veeam uses port 902 in network mode for replication which was already assigned to a policy but set to TFO only as it's generally just console traffic.  Seeing 12 Megabit peaks from a T-1 Line.. Nice!

RemoteCiscoWaas#show stat con | incl 902

196038 10.30.1.44:49542 10.30.2.62:902 1c:c1:de:7f:de:cc TDL 98.6%
196050 10.30.1.44:49552 10.30.2.62:902 1c:c1:de:7f:de:cc TDL 84.6%

Hi,
could you send me the veeam forum page or give me some more details? i had all the policies configured, but still with no good compression.

Hi,

Without knowing the exact Veeam page, I think that that you must configure you WAAS system to allow addition optimization on the TCP port used by Veeam.

So create a policy in CM, which will apply additional Optimization policies (like LZ and DRE) on the Veeam sessions, based on IP-addresses and TCP port numbers.
